Medicare Expenditures Among Nursing Home Residents With Advanced Dementia

BACKGROUND Nursing home residents with advanced dementia commonly experience burdensome and costly interventions (eg, tube feeding) that may be of limited clinical benefit. To our knowledge, Medicare expenditures have not been extensively described in this population. METHODS Nursing home residents with advanced dementia in 22 facilities (N = 323) were followed up for 18 months. Clinical and health services use data were collected every 90 days. Medicare expenditures were described. Multivariate analysis was used to identify factors associated with total 90-day expenditures for (1) all Medicare services and (2) all Medicare services excluding hospice. RESULTS Over an 18-month period, total mean Medicare expenditures were

12,000 for 5.5% of these periods. The largest proportion of Medicare expenditures were for hospitalizations (30.2%) and hospice (45.6%). Among decedents (n = 177), mean Medicare expenditures increased by 65% in each of the last 4 quarters before death owing to an increase in both acute care and hospice. After multivariable adjustment, not living in a special care dementia unit was a modifiable factor associated with higher total expenditures for all Medicare services. Lack of a do-not-hospitalize order, tube feeding, and not living in a special care unit were associated with higher nonhospice Medicare expenditures. CONCLUSIONS Medicare expenditures among nursing home residents with advanced dementia vary substantially. Hospitalizations and hospice account for most spending. Strategies that promote high-quality palliative care may shift expenditures away from aggressive treatments for these patients at the end of life.

Mapping Health Status Measures to a Utility Measure in a Study of Nursing Home Residents With Advanced Dementia

BACKGROUND Treatment of acute heart failure in the emergency department (ED) or observation unit is an alternative to hospitalization. Both ED management and observation unit management have been associated with reduced costs and may be used to avoid penalties related to rehospitalizations. The purpose of this study was to examine trends in ED visits for heart failure and disposition following such visits. METHODS We used the National Hospital Ambulatory Medical Care Survey, a representative sample of ED visits in the United States, to estimate rates and characteristics of ED visits for heart failure between 2002 and 2010. The primary outcome was the discharge disposition from the ED. Regression models were fit to estimate trends and predictors of hospitalization and admission to an observation unit. RESULTS The number of ED visits for heart failure remained stable over the period, from 914,739 in 2002 to 848,634 in 2010 (annual change -0.7%, 95% CI -3.7% to +2.5%). Of these visits, 74.2% led to hospitalization, wheras 3.1% led to observation unit admission. The likelihood of hospitalization did not change during the period (adjusted prevalence ratio 1.00, 95% CI 0.99-1.01 for each additional year), whereas admission to the observation unit increased annually (adjusted prevalence ratio 1.12, 95% CI 1.01-1.25). We observed significant regional differences in likelihood of hospitalization and observation admission. CONCLUSIONS The number of ED visits for heart failure and the high proportion of ED visits with subsequent inpatient hospitalization have not changed in the last decade. Opportunities may exist to reduce hospitalizations by increasing short-term management of heart failure in the ED or observation unit.

Outcomes with Angiotensin-converting Enzyme Inhibitors vs Other Antihypertensive Agents in Hypertensive Blacks

We performed a retrospective cohort study of patients with chronic obstructive lung disease (COPD) on long-term oxygen treatment (LTOT) who received invasive mechanical ventilation for COPD exacerbation. Of the 4791 patients, 23% died in the hospital, and 45% died in the subsequent 12 months. 67% of patients were readmitted at least once in the subsequent 12 months, and 26.8% were discharged to a nursing home or skilled nursing facility within 30 days. We conclude that these patients have high mortality rates, both in-hospital and in the 12 months postdischarge. If patients survive, many will be readmitted to the hospital and discharged to nursing home. These potential outcomes may support informed critical care decision making and more preference congruent care.

Association of weekend continuity of care with hospital length of stay.

BACKGROUND Clinical trial evidence suggests poorer outcomes in blacks compared with whites when treated with an angiotensin-converting enzyme (ACE) inhibitor-based regimen, but this has not been evaluated in clinical practice. OBJECTIVES This study evaluated the comparative effectiveness of an ACE inhibitor-based regimen on a composite outcome of all-cause mortality, stroke, and acute myocardial infarction (AMI) in hypertensive blacks compared with whites. METHODS We conducted a retrospective cohort study of 434,646 patients in a municipal health care system. Four exposure groups (Black-ACE, Black-NoACE, White-ACE, White-NoACE) were created based on race and treatment exposure (ACE or NoACE). Risk of the composite outcome and its components was compared across treatment groups and race using weighted Cox proportional hazard models. RESULTS Our analysis included 59,316 new users of ACE inhibitors, 47% of whom were black. Baseline characteristics were comparable for all groups after inverse probability weighting adjustment. For the composite outcome, the race treatment interaction was significant (p = 0.04); ACE use in blacks was associated with poorer cardiovascular outcomes (ACE vs. NoACE: 8.69% vs. 7.74%; p = 0.05) but not in whites (6.40% vs. 6.74%; p = 0.37). Similarly, the Black-ACE group had higher rates of AMI (0.46% vs. 0.26%; p = 0.04), stroke (2.43% vs. 1.93%; p = 0.05), and congestive heart failure (3.75% vs. 2.25%; p < 0.0001) than the Black-NoACE group. However, the Black-ACE group was no more likely to develop adverse effects than the White-ACE group. CONCLUSIONS ACE inhibitor-based therapy was associated with poorer cardiovascular outcomes in hypertensive blacks but not in whites. These findings confirm clinical trial evidence that hypertensive blacks have poorer outcomes than whites when treated with an ACE inhibitor-based regimen.

Effects of ParentCorps in Prekindergarten on Child Mental Health and Academic Performance: Follow-up of a Randomized Clinical Trial Through 8 Years of Age

Background:Nursing home residents with advanced dementia commonly experience burdensome and costly interventions (eg, hospitalization) of questionable clinical benefit. To facilitate cost-effectiveness analyses of these interventions, utility-based measures are needed in order to estimate quality-adjusted outcomes. Methods:Nursing home residents with advanced dementia in 22 facilities were followed for 18 months (N=319). Validated health status measures ascertained from nurses at baseline, quarterly, and death (N=1702 assessments) were mapped to the Health Utilities Index Mark 2 [range, 1 (perfect health) to 0 (death); scores below 0 indicate states worse than death]. To assess validity, utility scores were compared between residents who did and did not receive burdensome interventions (parenteral therapy, percutaneous endoscopic gastrostomy tubes, and hospital transfers), residents with and without pneumonia, and residents who did and did not die at the last assessment. Results:Mean (±SD) Health Utilities Index Mark 2 utility score for the cohort was 0.165±0.060 (range, –0.005 to 0.215). Residents spent an average of 15.5% of their days with utilities <0.10. Lower utility scores were found among residents who received burdensome interventions (0.152±0.067 vs. 0.171±0.056; P=0.0003); had pneumonia (0.147±0.066 vs. 0.170±0.057; P=0.003); and were dying (0.163±0.057 vs. 0.180±0.055; P=0.006). Conclusions:It is feasible to map health status measures to utility-based measures for advanced dementia. This work will facilitate future cost-effectiveness analyses aimed at quantifying the cost of interventions relative to quality-based outcomes for patients with this condition.

Early Lessons on Bundled Payment at an Academic Medical Center

BACKGROUND Angiotensin-converting enzyme inhibitors are used widely in the treatment of patients with hypertension. However, their efficacy in hypertensive blacks when compared with other antihypertensive agents is not well established. METHODS We performed a cohort study of patients using data from a clinical data warehouse of 434,646 patients from New York Citys Health and Hospitals Corporation from January 2004 to December 2009. Patients were divided into the following comparison groups: angiotensin-converting enzyme inhibitors vs calcium channel blockers, angiotensin-converting enzyme inhibitors vs thiazide diuretics, and angiotensin-converting enzyme inhibitors vs β-blockers. The primary outcome was a composite of death, myocardial infarction, and stroke. Secondary outcomes included the individual components and heart failure. RESULTS In the propensity score-matched angiotensin-converting enzyme inhibitors vs calcium channel blocker comparison cohort (4506 blacks in each group), angiotensin-converting enzyme inhibitors were associated with a higher risk of primary outcome (hazard ratio [HR], 1.45; 95% confidence interval [CI], 1.19-1.77; P = .0003), myocardial infarction (HR, 3.40; 95% CI, 1.25-9.22; P = .02), stroke (HR, 1.82; 95% CI, 1.29-2.57; P = .001), and heart failure (HR, 1.77; 95% CI, 1.30-2.42; P = .0003) when compared with calcium channel blockers. For the angiotensin-converting enzyme inhibitors vs thiazide diuretics comparison (5337 blacks in each group), angiotensin-converting enzyme inhibitors were associated with a higher risk of primary outcome (HR, 1.65; 95% CI, 1.33-2.05; P < .0001), death (HR, 1.35; 95% CI, 1.03-1.76; P = .03), myocardial infarction (HR, 4.00; 95% CI, 1.34-11.96; P = .01), stroke (HR, 1.97; 95% CI, 1.34-2.92; P = .001), and heart failure (HR, 3.00; 95% CI, 1.99-4.54; P < .0001). For the angiotensin-converting enzyme inhibitors vs β-blocker comparison, the outcomes between the groups were not significantly different. CONCLUSIONS In a real-world cohort of hypertensive blacks, angiotensin-converting enzyme inhibitors were associated with a higher risk of cardiovascular events when compared with calcium channel blockers or thiazide diuretics.

Extended-release naltrexone opioid treatment at jail reentry (XOR)

OBJECTIVE The purpose of this study was to evaluate the association of physician continuity of care with length of stay, likelihood of weekend discharge, in-hospital mortality and 30-day readmission. DESIGN A cohort study of hospitalized medical patients. The primary exposure was the weekend usual provider continuity (UPC) over the initial weekend of care. This metric was adapted from an outpatient continuity of care index. Regression models were developed to determine the association between UPC and outcomes. SETTING An academic medical center. MAIN OUTCOME MEASURE Length of stay which was calculated as the number of days from the first Saturday of the hospitalization to the day of discharge. RESULTS Of the 3391 patients included in this study, the prevalence of low, moderate and high UPC for the initial weekend of hospitalization was 58.7, 22.3 and 19.1%, respectively. When compared with low continuity of care, both moderate and high continuity of care were associated with reduced length of stay, with adjusted rate ratios of 0.92 (95% CI 0.86-1.00) and 0.64 (95% CI 0.53-0.76), respectively. High continuity of care was associated with likelihood of weekend discharge (adjusted odds ratio 2.84, 95% CI 2.11-3.83) but was not significantly associated with mortality (adjusted odds ratio 0.72, 95% CI 0.29-1.80) or readmission (adjusted odds ratio 0.88, 95% CI 0.68-1.14) when compared with low continuity of care. CONCLUSIONS Increased weekend continuity of care is associated with reduced length of stay. Improvement in weekend cross-coverage and patient handoffs may be useful to improve clinical outcomes.
